Final answer:
Under the Articles of Confederation, the federal government could suggest programs to states, but states were not obligated to cooperate or fund these initiatives.
Step-by-step explanation:
Under the Articles of Confederation, the federal government did not have the power to impose taxes. It had to rely on the states to provide funds for its expenses. Therefore, Option D is not possible. The correct answer is Option B: Suggest the program to states, and they could decide to cooperate or not.
Under the Articles of Confederation, the federal government did not have the authority to require participation or contributions from the states. It could only make suggestions and rely on the states' willingness to cooperate. This lack of centralized power was one of the weaknesses of the Articles of Confederation.
Under the Articles of Confederation, if the federal government wanted to start a program to help farmers improve their methods, it could only suggest the program to states, and they could decide to cooperate or not. The national government lacked the power to impose taxes and therefore could not use tax money from the states to fund any programs directly. It primarily operated on funds provided voluntarily by states and had limited influence over state activities, including agricultural programs. States were also under no obligation to honor requests for participation in programs such as contributions of money or research time from state universities.
